So as stated in my previous thread I'm planning a swap into my 36 Diamond T but not sure what motor to run was thinking LB7 because it's older may be more prevalent and easier. The LLY would be nice because I have a DD LLY and if needed parts in a pinch they would be there and lastly the LBZ I was talking with a guy that sells used duramax motors and he said LLY's are harder to come by and the LBZ might be my best option for readily available parts. Any thoughts? I'd be doing a ZF6 behind it. -John
